摘要 目的观察血肿穿刺清除术对大鼠脑出血灶周组织中白细胞介素6(IL-6)和肿瘤坏死因子α(TNF-α)表达的影响。方法将90只Wistar大鼠随机分为对照组、模型组和手术组各30只,模型组和手术组采用自体不凝血注入大鼠尾状核的方法制备大鼠脑出血模型,对照组注射等量生理盐水;在建模后6、12、24、48、72 h,手术组行血肿穿刺清除术(每次6只)。手术组在术后4 h、对照组和模型组在建模后6、12、24、48、72 h断头处死大鼠各6只,取尾状核平面切片,采用免疫组化SP法测定脑出血灶周组织中的IL-6、TNF-α。结果与对照组比较,模型组和手术组脑出血后6 h,大鼠脑出血灶周组织中TNF-α、IL-6阳性表达细胞数增加,分别于24、72 h达高峰(P均<0.05)。手术组大鼠脑出血灶周组织中IL-6、TNF-α阳性表达细胞数少于同时点的模型组、多于同时点的对照组(P均<0.05),且造模后6 h手术的大鼠脑出血灶周组织中TNF-α、IL-6阳性表达细胞数均较其他时点手术的大鼠少(P均<0.05)。结论血肿穿刺清除术可减少大鼠脑出血灶周组织中IL-6、TNF-α的表达,其中出血后6 h行血肿清除术的大鼠脑出血灶周组织中IL-6、TNF-α的表达最少。
